4-8 QoS Setting
Here you can configure QoS policy priority mode and CoS (Class of Service) configuration. QoS
(Quality of Service) refers to mechanisms in the network software that make the actual determination of
which packets have priority. CoS refers to feature sets, or groups of services, that are assigned to users
based on company policy. If a feature set includes priority transmission, then CoS winds up being
implemented in QoS functions within the routers and switches in the network. In an enterprise network,
class of service (CoS) differentiates high-priority traffic from lower-priority traffic. Tags may be added to
the packets to identify such classes, but they do not guarantee delivery as do quality of service (QoS)
functions, which are implemented in the network devices.
